The 23-year-old beauty, who has modeled for Dark & Lovely, told GMA that she wants to make it big in modelling and hopes to land a contract someday with Victoria’s Secret.

“As soon as I was born, I’ve been wanting to do this,” Murphy told GMA. But she had to overcome her naturally shy personality to pursue her dream.

“If you look at the old pictures, I’m in the back of everybody,” the budding catwalker elaborated. “As I got older, I was like, ‘Bria you can’t want to model, and not want to be out there and be the center of attention.'”

While Murphy has overcome that obstacle, she still faces the pressures of an industry that she says drives women to stay rail thin at all costs.

“Lots of girls get addicted to drugs, and anorexia,” Murphy said, detailing, “there’s a whole list of things, because there’s a lot of pressure to be perfect.”

What is the most extreme diet she’s heard of?

“I’ve heard of people eating the cotton balls with the orange juice,” Murphy said. “They dip it in the orange juice and then they eat the cotton balls to help them feel full.”

Murphy added that she is naturally “small,” but that she “can gain weight,” so the pressure to be thin is not one she totally escapes.

Despite being the daughter of a major Hollywood star, Murphy must brave these challenges, in addition to the constant rejection that those in the fashion industry in front of the camera face.

“It’s your job to go into a room and some people will just say no without an explanation,” she said, “and some will be like, ‘You’re nose is too big, you’re butt’s too big, uh, your legs are flabby,’ but that’s their job, so you just can’t take it personal.”
